rants and (hopefully) useful info
While we all know how to add tasks using crontab -e or check current tasks using crontab -l, doing things this way can sometimes be a bit inconvenient (eg. if you’re mid-script). Adding via CLI can be done in the CentOS implementation like this … echo “* * * * * \$HOME/path/to/scriptOrApp.sh” >> /var/spool/cron/USERNAME; ……
Most often, if you’d like to know what your router IP address is, you need to have access to its interface via a browser, or similar such gadgets. Here’s a few convenient one-liners which will give you that info more easily/conveniently… #get WAN address dig +short myip.opendns.com @resolver1.opendns.com #get DHCP server address(es)… cat /var/lib/dhcp/dhclient*leases \…
Maybe I did it wrong, but the way my various LANs and systems are set up, I can’t always get to a few of my endpoints without a 2 step process of doing an SSH to 1 “server”, and then from there, doing a 2nd SSH to the desired endpoint. eg. If the remote endpoint…
There are MANY such guides on the internet – this one is probably not any different or better than those. You should read the man-page for SSH-keygen. THE best resource/book that I have read on the topic is SSH Mastery – Michael W Lucas. His books are generally some of the best on each topic…
On the topic of minimalist… I like a small footprint…and I stumbled upon some numbers and according to the “internet”… Plain Openbox only: 58 MB XFCE: 89 MB (with default configuration of Debian) LXDE (gtk+ 2 version): 78 MB (add 20 MB to openbox) On my “fully loaded” desktop station, including/running LibreOffice and a bunch…
For the record – these are lookups – NOT my creations. I will add more as I go #Backup & clear history DATE=`date +%Y%m%d-%H%M` mv ~/.zsh_history{,.$DATE} cat /dev/null > ~/.zsh_history #HDD space (without clutter) df -h | grep -v “tmp\|udev” #send contents into a file (you need to \escape any \$variables within the CONTENTS+COMMANDS) cat
For a while, I preferred ArchLinux as my personal Desktop Workstation. However, I found a few instances where I was not able to get certain apps to work reliably. I started looking into alternatives which would be equally light and configurable. This was where I decided against ubuntu – since it wanted to make all…
CentOS VERY solid and stable. I have several servers that have uptime of >500days (the very few incidences of downtime were from power issues, not OS). I did get hacked a couple of times before I learned how to use iptables adequately. Debian SOMETIMES, compatibility calls for non-CentOS. I am not a fan of…
My objective when I started experimenting with Desktop linux, was to mimic a WinX station. I would hazard a guess that this is the most likely scenario for anyone switching away from M$-windows. If they can’t keep doing their work “productively” – they are NOT going to be interested in whether the propellor heads think…
To say the very least, this is a loaded question that often sets of flaming wars and petty squabbling – neither of which are useful. My objective is to offer some alternative to M$ for anyone who wants to learn and try new things, and escape the clutches of the proprietary BS we are…
